There was never any possibility that Sarah Palin would run for VP with Romney. She is an evangelical, strong on 2nd amendment and right to life, as well as separation of church and state, but not the exclusion of freedom of worship.
I never seriously thought that she would accept a vp slot under Romney. But I really don’t know what she is planning.
I think we can see why Palin did not run. She saw the game was rigged. The attack on Bain terrified the Establishment because it reveals how affairs have been handled for the past twenty years. Mitt is really just a small time player, but huge fortunes have been made by financial institutions entering into the same kind of arrangements. The Democrats are essentially right that the Republicans were mainly responsible, but they have been players, too, and their attempts to stay in power have cranked up engine speed so high that the train might not make the next curve.
